Models affected	8BL-SC94; 8BL-SC86
Units affected	1961
Defect	In the engine, due to inappropriate design of the piston and top ring, the gap between the piston and top ring is wide. If the engine repeatedly decelerates using engine braking from a high-revolution state, engine oil may be drawn into the combustion chamber and burn, potentially increasing oil consumption. As a result, abnormal noise may occur due to poor oil lubrication. If use is continued, the engine may be damaged while driving, leading to the rear wheel locking and causing a fall, or potentially a fire.
Component	Engine unit
Recall type	Vehicle
Remedy	For all vehicles, replace the piston and top ring with improved parts. Additionally, inspect the engine, and if abnormal noise is present, replace the entire engine assembly.
